Some laptops carry a MediaTek power table in their firmware, and the
driver reads it to set a transmit limit for each frequency range.  It
only fills in the ranges themselves when it registers the device.

The startup step that does this existed already, but it never programmed
anything.  Two recent commits made it run a regulatory update instead,
which sets the limits on the way through, long before registration.

As a result, on a machine that has the table the driver reads through an
empty pointer and the interface never appears:

  BUG: kernel NULL pointer dereference, address: 0000000000000004
  RIP: 0010:mt792x_init_acpi_sar_power
  Call Trace:

   mt7921_regd_update
   mt7921_run_firmware
   mt7921e_mcu_init
   mt7921_init_work

Skip it when the ranges are missing. They are applied again once the
device is up, which is where they came from before.

Treat an out-of-range CLC index as newer firmware rather than a
malformed image. linux-firmware 20260810 ships MT7922 records with
idx 3, and rejecting them made mt7921e fail to probe.

Keep the record-length checks, and report those as errors so a
truncated table is visible instead of a silent retry loop.

<title>treewide: refresh kmalloc_obj() conversions</title>

This is another run of the Coccinelle script for converting kmalloc()
family of allocations to kmalloc_obj() via the existing rules in
scripts/coccinelle/api/kmalloc_objs.cocci

This catches both the set of kmalloc() uses added since the first
kmalloc_obj() conversions in v7.0 and adds a large group missed in the
first pass due to Coccinelle not interacting well with the cleanup.h
scoped_...() family of macros[1]. I worked around this with spatch's
"--macro-file" argument to a file with all the scoped_...() macros mapped
to Coccinelle's YACFE_ITERATOR[2] as that was the closest viable control
flow indicator I could find.

Build tested allmodconfig on x86, arm64, arm, loongarch, mips, powerpc,
riscv, and s390 with no new warnings.

<id>d51fc9d4cd6eb18ac82913d83ecf7bd8c85f71ee</id>
<content type='text'>
The way power sequencing works means that a call to pwrseq_power_on()
does not necessarily result in the pwrseq target being powered-on at
that time: it may have already been powered on before. Similarly: a call
to pwrseq_power_off() does not have to result in an actual powering off
of resources: there may still be other users that requested a power-on
before.

We will also introduce the concept of "non-controllable" pwrseq targets
soon which further increases the disconnect between the naming
convention and the actual semantics.

What consumers of pwrseq descriptors actually do is: they *vote* for a
powering on of a given target or retract that vote. These operations
could be called get/put in line with runtime PM but this could become
confusing since we already provide pwrseq_get/put() for a different
purpose. pwrseq_vote_on/off() also have been rejected as unusual in
the tree.

Change the name of the two functions to pwrseq_enable/disable() which
better reflects their purpose and semantics and also mirrors other
enable-counted resources like regulators and clocks. No functional change
intended.

If at any point users need to know *when* the exact power event happens,
we can provide that information in the form of a notifier.

This reverts commit 13b7e6a96a005c656d38f3da51581deaf9866375.

That commit made mt76_dma_cleanup() disable every RX NAPI instance before
deleting it, to silence WARNs in __netif_napi_del_locked() and
page_pool_disable_direct_recycling() seen when unloading mt7915e with an
MT7916.

On mt7921e and mt7925e the same instances are already disabled earlier,
in mt7921e_unregister_device() and mt7925e_unregister_device(), which
only afterwards call mt792x_dma_cleanup() -&gt; mt76_dma_cleanup().  Each
instance is therefore disabled twice, and napi_disable() is not
idempotent: on return it leaves NAPIF_STATE_SCHED and NAPIF_STATE_NPSVC
set, so the second call spins in usleep_range() forever, waiting for bits
that nobody will clear.

mt7921_pci_shutdown() and mt7925_pci_shutdown() reuse the remove path, so
this is hit on every reboot, poweroff and module unload.  It is silent:
the stuck task keeps sleeping and rescheduling, so neither the hung task
detector nor the lockup detectors fire, and the last line on the console
is "systemd-shutdown[1]: Rebooting."

  task:modprobe        state:D stack:25720 pid:7954  tgid:7954
  Call Trace:

   do_syscall_64+0x11c/0x6d0
   entry_SYSCALL_64_after_hwframe+0x76/0x7e
   &lt;/TASK&gt;

Dropping the two driver-side loops instead was tried and rejected: with
them gone, the RX poll can reach mt76_token_release() via
PKT_TYPE_TXRX_NOTIFY and mt7921_mac_tx_free() while
mt76_connac2_tx_token_put() is running idr_destroy(&amp;dev-&gt;token) outside
token_lock, which is a use-after-free rather than a hang [1].

Revert for now, so that reboot, poweroff and module unload work again.
The WARNs on mt7915e are a less severe problem than an unbootable
machine, and fixing them belongs in the drivers that delete the NAPI
instances, where each one can pick a point that is safe for its own
teardown order, rather than in the shared mt76_dma_cleanup().

[ This is the "landing soonish" known regression fix mentioned in the
  previous networking merge commit       - Linus ]
